This was the second installment of @prokarius' Choose Your Own Adventure. Just like the previous one, this is just as irritating. We start off by connecting to the port.

root@ctf:~# nc ctf.pwn.sg 11006
Your position: 0
As you float, the pointer on your instrument reads 1068077148.
Where would you like to float?
1 to float backwards.
2 to float forwards.
9 to float into the void. (Quit)

Seems fairly basic, further investigation leads us to know that no matter what, we can only move forward and backwards a total of 11 times, meaning only 11 "pointers" are ever returned. Let's start off by gathering all the pointers we have.

What now? Well, it's a @prokarius challenge, so the next step would be to figure out if those numbers mean anything. SPOILER, they do! They are all constants! How does that help us though? Let's try replacing them with the different symbols used to replace them in Physics!

That all comes down to forming plancks0bar, let's see if we can find the value of planck's bar! According to https://physics.info/constants, h bar = 1.05457182E−34. Unfortunately, that's not the flag... maybe convert it back to an integer?
